This new computerized animation from the creators of Ice Age is set in an imaginary world of robots where comical groups of bolts are the protagonists in a revolt against shady characters to gain their rights to a better life. Rodney Copperbottom is a genial but poor robot that keeps losing his parts but grows by replacing them with hand me downs from his better off cousins. Armed with a special inventive talent, he tries his luck in Robot City, where, amidst gags and film citations, he finds loyal companions and realizes his dreams.
